세계의 공기질 모니터링 시장 규모는 2025년 55억 달러에 달했습니다. IMARC 그룹은 향후 2026-2034년 연평균 복합 성장률(CAGR) 6.20%로 성장할 전망이며, 2034년까지 95억 달러에 달할 것으로 예측했습니다. 도시화 및 산업화의 가속화, 공중보건에 대한 오염의 유해한 영향에 대한 인식 증가, 기능성 향상을 위한 대기 모니터링 시스템에 사물 인터넷(IoT) 및 인공지능(AI)의 통합 등이 시장 성장을 가속하는 주요 요인입니다.
도시화 및 산업화의 진전
유엔개발계획(UNDP)의 '중국통계연감(2023년판)'에 따르면 영구 거주를 목적으로 한 도시화 비율은 1982년 이후 3배로 증가했으며 2023년에는 66.2%에 달했습니다. 도시의 확대 및 산업 활동 증가는 대기 오염 레벨의 악화를 초래하고 있어, 엄격한 모니터링 및 관리 대책이 요구되고 있습니다. 도시 지역에서는 교통 배출 가스, 건설 분진, 산업 폐수와 관련된 문제에 직면하여 대기 질의 악화를 초래합니다. 지자체 당국과 민간 기업은 오염 수준을 추적하고 효과적인 완화 조치를 취함으로써 이러한 문제를 해결하기 위해 고급 공기질 모니터링 시스템을 활용합니다. 산업 지역에서는 환경 법규를 준수하고 환경에 미치는 영향을 줄이기 위해 배출 가스의 지속적인 추적이 필요합니다.
증가하는 환경 의식 및 건강에 대한 우려
대기오염 및 호흡기 질환이나 심장병 등 다양한 건강 문제와의 관련성을 나타내는 증거가 늘어나고 있기 때문에 개인이나 행정 기관은 대기 오염 대책에 적극적으로 임하고 있습니다. 또한 언론의 노출 증가와 계발 활동으로 인해 오염원과 건강 위험에 대한 국민의 인식이 높아지고 있습니다. 이 의식 증가는 주거용 및 상업용 공기질 모니터링 수요를 촉진할 뿐만 아니라 보다 엄격한 대기질 기준과 지속적인 모니터링을 의무화하는 정책 변경에도 영향을 미치고 있습니다. 2024년 6월, 인도 트리플라주 아가르타라에서는 중앙공해관리국(CPCB)의 서버와 연동하는 실시간 공기질 모니터링 시스템을 2기 설치했습니다. 이를 통해 주민들은 ‘Sameer’ 앱을 통해 오염 수준을 추적할 수 있어 도시화와 계절 변화에 의해 악화되는 대기질 문제에 대한 대책, 투명성 향상, 시민 의식 계몽을 목적으로 한 프로젝트입니다.
기술적 진보 및 통합
모니터링 시스템에 대한 사물 인터넷(IoT)과 인공지능(AI)의 통합은 데이터 수집, 분석, 보고 방법을 변화시키고 있습니다. 이러한 기술은 즉각적인 모니터링을 가능하게 하고 정확하고 상세한 데이터를 제공합니다. 이는 신속한 의사결정과 효율적인 오염 대책의 구현에 필수적입니다. 고급 센서와 고급 분석 장비는 미량 오염물질 농도조차도 확인할 수 있어 공기질 평가의 정확성 향상에 기여합니다. 게다가 개인용 및 실내 공기질 관리 수요 증가에 대응해, 휴대형, 웨어러블형 공기질 모니터의 보급이 진행되고 있습니다. 이러한 기술 혁신은 기능성과 사용 용이성 향상, 산업 및 주택 환경 등 다양한 분야에서의 활용 확대를 통해 공기질 모니터링 기기의 성능을 높이고 있습니다. 2023년 Siemens Co., Ltd.는 중소규모 건물을 모니터링하고 에너지 효율을 향상시키고 온도와 습도를 실시간으로 업데이트하여 공기질 추적을 제공하는 IoT 솔루션인 Connect Box를 발표했습니다. Siemens Xcelerator 제품군의 이 신제품은 건물 관리를 단순화하고 실내 공기 품질을 향상시키기 위해 설계되었습니다.
The global air quality monitoring market size reached USD 5.5 Billion in 2025. Looking forward, IMARC Group expects the market to reach USD 9.5 Billion by 2034, exhibiting a growth rate (CAGR) of 6.20% during 2026-2034. The growing pace of urbanization and industrialization, increasing public awareness about the harmful impacts of pollution on health, and incorporation of internet of things (IoT) and artificial intelligence (AI) in air monitoring systems to improve functionality are some of the factors impelling the market growth.
Rising Urbanization and Industrialization
The rate of urbanization for permanent residence tripled since 1982, reaching 66.2% in 2023, as per the "China in Numbers (2023)" report by the United Nations Development Programme (UNDP). The expansion of cities and the rise in industrial activities are resulting in increased air pollution levels, necessitating stringent monitoring and control measures. Urban areas are dealing with issues related to traffic emissions, construction dust, and industrial discharges, leading to a decline in air quality. Municipal authorities and private enterprises are using advanced air quality monitoring systems to deal with these problems by tracking pollution levels and implementing effective mitigation strategies. Industrial areas are required to consistently track emissions for adhering to environmental laws and reducing their impact on the environment.
Growing Environmental Awareness and Health Concerns
Individuals and governing bodies are actively working to address air pollution because of the growing evidence linking poor air quality to a range of health problems, such as respiratory illnesses and heart issues. Furthermore, increased media exposure and educational initiatives are raising public awareness about pollution origins and health dangers. This growing awareness is not only driving the demand for residential and commercial air quality monitors but also influencing policy changes that mandate stricter air quality standards and continuous monitoring. In June 2024, Agartala in Tripura, India, set up two real-time air quality monitoring systems that are linked to Central Pollution Control Board (CPCB) servers, allowing residents to track pollution levels through the Sameer app. This project aimed to tackle air quality problems worsened by urbanization and seasonal changes, enhancing transparency and public awareness.
